CAS: Chemistry

Sample Pathways

Below is an example of a four-year plan of a College of General Studies student pursuing a Bachelor of Arts in Chemistry at the College of Arts and Sciences (CAS). Students will work with their CGS academic advisors and the chemistry department to plan their own pathway to a chemistry degree.

Gap Semester Recommended external course: Calculus I (equivalent to CAS MA 123) Note: Prior approval must be granted for external coursework. Students must consult with their CGS academic advisor before enrolling in classes.

**CAS CH 225 has a prerequisite of CAS CH 101, CAS CH 109, or CAS CH 111. Students who have completed CAS MA 123 and CAS MA 124 and who have completed AP or IB Chemistry are well suited to take CAS CH 225 concurrently with CAS CH 109. Students who have questions about CAS CH 225 should connect with CAS Advising at the information listed below under Academic Advising.

^Choose your electives carefully to fulfill any remaining BU Hub requirements. You will find a list of all of the courses that carry Hub units on the University’s BU Hub website. External courses are not eligible for Hub general education credit.

This is a sample pathway to be used in consultation with your CGS Academic Advisor.

It is subject to change according to course availability and individual circumstances.
